For Verizon webOS 2.1.0, Skype Mobile is part of the carrier apps of which only work on the Verizon Data network (it is also backwards compatible with the Verizon PrePlus running webOS 2.1.0 (build 284 or 285).
For WR/ROW or meta doctored Verizon webOS 2.2.4, Skype is updated to Direct Skype, which again is not an app but a synergy connector, also it works over WiFi or a carrier data network.
Both add a contact plugin, im, voice (but no video) calls.
You use the phone app for calls, contacts for the contacts and messaging for ims.
